FUNDAMENTAL TRIGONOMETRIC IDENTITIES

Instruction: For each item, drag the number or mathematical expression given on the right side of the display (or below) into the correct box so that an identity is formed.

Q: 1. \(\cos\theta \sec\theta\) = [...]

2. \(\sin\theta\)[...] = \(1\)

3. [...]\(\cot\theta\) = \(1\)

4. \(\tan\theta\) = [...]/\(\cos\theta\)

5. \(\cot\theta\) = [...]/\(\sin\theta\)

6. \(\cos^2\theta + \sin^2\theta\) = [...]

7. [...] + \(\tan^2\theta\) = \(\sec^2\theta\)

8. [...] + \(1\) = \(\csc^2\theta\)
